# Setup
For security reasons regarding CORS, your hosted instance of Materialious must serve as the value for the `Access-Control-Allow-Origin` header on Invidious.

Invidious doesn't provide a simple way to modify CORS, so this must be done with your reverse proxy.

## Step 1: Reverse proxy
### Caddy example
```caddyfile
invidious.example.com {
	@cors_preflight {
		method OPTIONS
	}
	respond @cors_preflight 204

	header Access-Control-Allow-Credentials true
        header Access-Control-Allow-Origin "https://materialious.example.com" {
		defer
	}
        header Access-Control-Allow-Methods "GET,POST,OPTIONS,HEAD,PATCH,PUT,DELETE"
        header Access-Control-Allow-Headers "User-Agent,Authorization,Content-Type"

	reverse_proxy localhost:3000
}

materialious.example.com {
	reverse_proxy localhost:3001
}
```

### Nginx example
```nginx
server {
    listen 80;
    server_name invidious.example.com;

    location / {
        if ($request_method = OPTIONS) {
            return 204;
        }

        proxy_hide_header Access-Control-Allow-Origin;
        add_header Access-Control-Allow-Credentials true;
        add_header Access-Control-Allow-Origin "https://materialious.example.com" always;
        add_header Access-Control-Allow-Methods "GET, POST, OPTIONS, HEAD, PATCH, PUT, DELETE" always;
        add_header Access-Control-Allow-Headers "User-Agent, Authorization, Content-Type" always;

        proxy_pass http://localhost:3000;
    }
}

server {
    listen 80;
    server_name materialious.example.com;

    location / {
        proxy_pass http://localhost:3001;
    }
}
```
### Nginx Proxy Manager example
1. Tab: Details -  Create a new proxy host with SSL on (Let's Encrypt or your own certificate).
2. Tab: Custom locations, fill in IP and port. Click gear icon to add some security headers.

**Add:**
```nginx
    if ($request_method = OPTIONS) {
      return 204;
    }

    proxy_hide_header Access-Control-Allow-Origin;
    add_header Access-Control-Allow-Credentials true;
    add_header Access-Control-Allow-Origin "https://materialious.example.com" always;
    add_header Access-Control-Allow-Methods "GET, POST, OPTIONS, HEAD, PATCH, PUT, DELETE" always;
    add_header Access-Control-Allow-Headers "User-Agent, Authorization, Content-Type" always;
```
Click **Save**.

### Traefik example
Add this middleware to your Invidious instance:
```yaml
http:
  middlewares:
    materialious:
      headers:
        accessControlAllowCredentials: true
        accessControlAllowOriginList: "https://materialious.example.com"
        accessControlAllowMethods:
          - GET
          - POST
          - OPTIONS
          - HEAD
          - PATCH
          - PUT
          - DELETE
        accessControlAllowHeaders:
          - User-Agent
          - Authorization
          - Content-Type
```

### Invidious Companion support
The `VITE_DEFAULT_COMPANION_INSTANCE` environment variable allows you to specify a custom [Invidious Companion](https://github.com/iv-org/invidious-companion) instance.

To use this with Materialious, your Invidious Companion instance must be accessible with proper CORS headers. Fortunately, you can reuse the same reverse proxy configuration (with CORS modifications) that you applied to your Invidious instance—just apply it to your companion domain as well.

For example, if you're using Caddy, you can configure your companion domain like this:

```caddy
companion.example.com {
	@cors_preflight {
		method OPTIONS
	}
	respond @cors_preflight 204

	header Access-Control-Allow-Credentials true
	header Access-Control-Allow-Origin "https://materialious.example.com" {
		defer
	}
	header Access-Control-Allow-Methods "GET, POST, OPTIONS, HEAD, PATCH, PUT, DELETE"
	header Access-Control-Allow-Headers "User-Agent, Authorization, Content-Type"

	reverse_proxy localhost:3000
}
```

### Other
Please open a PR request or issue if you implement this in a different reverse proxy.

## Step 2: Invidious config
The following Invidious values must be set in your config.

- `domain:` - The reverse proxied domain of your Invidious instance.
- `https_only: true` - Must be set if you are using HTTPS.
- `external_port: 443` - Must be set if you are using HTTPS.


## Step 3: Docker
Please ensure you have followed the previous steps before doing this!

### Docker Compose

```yaml
---
services:
  materialious:
    image: wardpearce/materialious:latest
    restart: unless-stopped
    ports:
      - 3001:80
    environment:
      # No trailing backslashes!
      # URL to your proxied Invidious instance
      VITE_DEFAULT_INVIDIOUS_INSTANCE: "https://invidious.materialio.us"

      # URL to your proxied Companion instance
      VITE_DEFAULT_COMPANION_INSTANCE: "https://companion.materialio.us"

      # URL TO RYD
      # Leave blank to disable completely.
      VITE_DEFAULT_RETURNYTDISLIKES_INSTANCE: "https://returnyoutubedislikeapi.com"

      # URL to Sponsorblock
      # Leave blank to completely disable sponsorblock.
      VITE_DEFAULT_SPONSERBLOCK_INSTANCE: "https://sponsor.ajay.app"

      # URL to DeArrow
      VITE_DEFAULT_DEARROW_INSTANCE: "https://sponsor.ajay.app"

      # URL to DeArrow thumbnail instance
      VITE_DEFAULT_DEARROW_THUMBNAIL_INSTANCE: "https://dearrow-thumb.ajay.app"

      # Look at "Overwriting Materialious defaults" for all the accepted values.
      VITE_DEFAULT_SETTINGS: '{"themeColor": "#2596be","region": "US"}'
```

### Overwriting Materialious defaults
Materialious allows you to overwrite the default values using `VITE_DEFAULT_SETTINGS`, see [SETTINGS](./SETTINGS.md) for more details.

**Please note:** These overwrites only apply on 1st load & won't replace existing configuration stored in browser local storage.

## Step 4 (Optional, but recommended): Self-host RYD-Proxy

### Step 1: Docker compose
Add the following to your docker compose file.

#### With TOR (Recommended)
```yml
tor-proxy:
  image: 1337kavin/alpine-tor:latest
  restart: unless-stopped
  environment:
    - tors=15

ryd-proxy:
  image: 1337kavin/ryd-proxy:latest
  restart: unless-stopped
  depends_on:
    - tor-proxy
  environment:
    - PROXY=socks5://tor-proxy:5566
  ports:
    - 3003:3000
```
#### Without TOR
```yml
ryd-proxy:
  image: 1337kavin/ryd-proxy:latest
  restart: unless-stopped
  ports:
    - 3003:3000
```

### Step 2:
Reverse proxy RYD-Proxy.

#### Caddy example
```caddy
ryd-proxy.example.com {
  header Access-Control-Allow-Origin "https://materialious.example.com" {
      defer
  }
  header Access-Control-Allow-Methods "GET,OPTIONS"
  reverse_proxy localhost:3003
}
```

#### Nginx example
```nginx
server {
    listen 80;
    server_name ryd-proxy.example.com;

    location / {
        add_header Access-Control-Allow-Origin "https://materialious.example.com" always;
        add_header Access-Control-Allow-Methods "GET, OPTIONS" always;
        proxy_pass http://localhost:3003;
    }
}
```

#### Traefik example
Add this middleware to your RYD-Proxy instance:
```yaml
http:
  middlewares:
    ryd-proxy:
      headers:
        accessControlAllowOriginList: "https://materialious.example.com"
        accessControlAllowMethods:
          - GET
          - OPTIONS
```

### Step 3:
Modify/add `VITE_DEFAULT_RETURNYTDISLIKES_INSTANCE` for Materialious to be the reverse proxied URL of RYD-Proxy.

## Step 5 (Optional, but recommended): Self-host Invidious API extended

### Step 1: Docker compose
Add the following to your docker compose

```yaml
services:
  api_extended:
    image: wardpearce/invidious_api_extended:latest
    restart: unless-stopped
    ports:
      - 3004:80
    environment:
      api_extended_postgre: '{"host": "invidious-db", "port": 5432, "database": "invidious", "user": "kemal", "password": "kemal"}'
      api_extended_allowed_origins: '["https://materialious.example.com"]'
      api_extended_debug: false

      # No trailing backslashes!
      api_extended_invidious_instance: "https://invidious.example.com"
      api_extended_production_instance: "https://syncious.example.com"
```

Add these additional environment variables to Materialious.
```yaml
VITE_DEFAULT_API_EXTENDED_INSTANCE: "https://syncious.example.com"
```

## Step 6 (Optional): Self-host PeerJS
[Read the official guide.](https://github.com/peers/peerjs-server?tab=readme-ov-file#docker)

Add these additional environment variables to Materialious.
```yaml
# Will differ depending on how you self-host peerjs.
VITE_DEFAULT_PEERJS_HOST: "peerjs.example.com"
VITE_DEFAULT_PEERJS_PATH: "/"
VITE_DEFAULT_PEERJS_PORT: 443
```
